Most hydration bladders on the market were designed decades ago and simply adapted for modern use. They prioritize storage, not performance—resulting in excess bulk, sloshing, drag, and unnecessary weight. Legacy bladders absorb sweat, slosh under load, and require removal for refilling or cleaning. RSVR takes a fundamentally different approach.

RSVR isn’t an iteration. It’s a redesign of hydration from the ground up.

Patent Pending Aerodynamic Design – Three-piece bladder contour conforms to the user’s back, minimizing standoff and reducing drag.

Optimized Storage Efficiency – Ergonomically shaped bladder stores more fluid in less volume compared to conventional designs.

Lightweight Construction – Lighter than all market competitors; harness with 1.8L bladder weighs only 320 grams (.7 lbs).

TRU Zip Waterproof Closure – Facilitates easy access for cleaning, maintenance, and servicing.

Hydrophobic Materials – Resist sweat absorption, reducing added water weight and maintaining hygiene.

HeatSync Technology – Direct fluid contact with the body enhances thermal regulation; optional foam back panel available for users preferring insulation.

Instant Refill Capability – Enables teammates to refill on the athlete’s back or allows fewer steps for self-refill and nutrient addition.

Real-Time Fluid Monitoring – Provides intuitive visibility and tactile feedback for water levels.

Configurable System – Modular design allows athletes to tailor capacity and functionality to their specific needs while minimizing unnecessary weight.

Anti-Slosh Baffles – Multiple internal baffles limit side-to-side fluid movement while maintaining a slim profile.

Under-Arm Hose Routing – Optimized hose position enhances accessibility and minimizes aerodynamic drag compared to over-the-shoulder designs.
